sorry i forgot to get back to you, yes, a 1.5y. but im also using the HET 1500kv in my other jetfan at about the same amps, and maybe even a little better performance in my het F-20

I noticed on the EJF website they recommend their 1680kv motor with their fan for 8s. Similarly, the Arc 36-75-1 is 1680kv and it gets between 2.5 to 2.75w on 8s with both the wemo and 9305 fans. Perhaps as KL said, the 1500kv is only good for Jetfan.

im sure the 1680 would work too .but then you'd need a 100 esc ,and flights would be shorter.the 1500 gives lower amps (80-85) and longer flight.seems to be a happy system ...think i could even use 4000 batts for a lighter airframe.

If you like the performance of Brent`s XL, I`d say go with the 1500kv. Nothing like duplicating a proven system to get exactly what you want, and you could always add a cell for a little extra kick when you want it.

It also has a lot to do with the pitch of the blades and the number of blades.

BTW. I am in search of a JetFan 90 if anyone has one they like to part with.

Hi guys,
I got very interest in this jet, but reading this post and the EJF building manual, saw many building tips and attentions points that are not difficult to solve using some quality materials and careful build.

The only thing that got real concern was the elevator stab flutter. And my idea is always use the simplest solution, removing the elevator moving part and replacing with a strait one. This way we have vey little change in the look and finishing with the difference between the center and the tip. A peace of trailing edge balsa glassed and painted is the easiest way to solve the problem.

Also I am thinking about using the HET 700-68 1500KV on Hyperion 4200 10S 45C batteries. What you suggestions about this setup?
